Abstract


 

The environmental dimension has advanced to become an important support of development through biodiversity and ecological balance. It works to conserve the resource and achieve sustainable development. Therefore, dealing with the agricultural sector in the perspective of economic return is not enough. It should advance to the social and environmental revenues to the country's security and the safety of the environment and the health of citizens. Climatic changes and their associated risks and effects such as desertification, land degradation, drought, and exchange swapping of sea water with ground water (salinity) are the most important phenomena that cause significant challenges on the cosmic level. These are no doubt that Libya be affected in agriculture and food sectors by these changes in the high rising of carbon emission. This study relied on evidence related to climatic and agricultural output of the major crops in Libya during the period from 1970 to 2012. The results of this study, using Granger Causality Test, showed a negative relationship between those variables, which leads to the need for radical changes in agricultural and water resources policies. We should focus on accelerating the growth of agricultural productivity and the forests and pastures to combat desertification using the modern technologies. The study also recommends the expansion of planting resistant varieties to salinity and heat and focus on research related to the development of these varieties.

Key words: climate changes, agriculture, food security, Libya, granger causality.
